EDWIN SPEAK ACHESON, ST. LOUIS, MISSOURI.

WIRE-SPLICER.

Application filed September 22, 1914.

To all whom it may concern:

Be it known that I, EDWIN S. AGHESON, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented new and useful Improvements in Wire- Splicers, of which the following is a specification.

This invention relates to wire splicing machines, and it has for its object to produce a device of this class, simple in construction and eflicient in operation, which shall be capable of making perfect splices of wires used in wire weaving machines and for other purposes.

A further object of the invention is to produce a machine of the class described in which the component parts will be simple in construction and of such a character as to be capable of being quickly and readily assembled together for operation.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings, Figure 1 is a view in side elevation of a wire splicing machine constructed in accordance with the invention. Fig. 2 is a view in side elevation of one of the side members 17. Fig. 3 is a detail view in elevation of one of the side members constituting the frame of the machine. Fig. 4 is a perspective detail view of the rotary cylinder or head of the machine. Fig. 5 is a perspective detail View of one of the bearing members for the rotary head. Fig. 6 is a detail View in elevation of the twisting blade detached from the head. Fig. 7 is a sectional detail view taken on the line 7-7 in Fig. 2. Fig. 8 is a detail view illustrating a splice resulting from the use of the improved machine.

Corresponding parts in the several figures are denoted by like characters of reference.

A truncated block 15 supported on a base 16 serves to support the upwardly extending Specification of Letters Patent.

side members 17 which constitute the frame of the machine, said side members being firmly bolted or otherwise secured 011 the block 15. Each side member 17 is provided at its upper end with a vertical slot or recess 18, the side walls of which are rounded at their upper ends and converge slightly in a downward direction for the reception of the wires that are to be spliced, the side walls of said recesses being spaced apart at their lower ends a distance equal to the diameter of the wire to be spliced.

Secured on the inner faces of the side members 17 adjacent to the upper ends thereof are bearing members consisting of split rings each composed of two halves 19 which together produce a ring having in the upper portion thereof an inlet slot 20 of ample width for the passage of the wires to be spliced. The bearing members are provided with flanges 21 serving to retain the cylindrical head 22 which is provided at the ends thereof with corresponding flanges 23. Said head is made of proper dimensions to fit snugly between the upper ends of the side members and to rotate freely in the bearing members, and it will be readily seen that by detaching one half of each bearing member, the head may be conveniently detached and replaced. The head 22 is provided intermediate the ends thereof with an enlarged portion or collar 24., the lower part of which is provided with a recess or socket 25 that is threaded for the reception of a handle 26, whereby the head may be rotated. The enlarged portion of the head, that is to say. that portion which is formed with the collar 24-, is provided with a transverse reccss 27 for the reception of a twisting blade 28 which may be secured detachably by means of pins 29 extending through the en larged portion or collar 24, said twisting blade being provided with a transverse notch or recess 30 of a shape and dimensionscon responding with the recesses 18 at the upper ends of the side members of the frame. The head 22 is also provided in the upper portion thereof witha longitudinal recess 31 for the accommodation of the wires that are to be twisted.

When the parts have been assembled, as best seen in Fig. 1, the ends of wires to be spliced may be readily introduced into the recesses 18 and 30, it being assumed that at the time of introduction of the wires, the said recesses are in alinement with each other. After the wires have been introduced, the head 22 may be rotated any desired number of times to properly twist the Wires to produce the required splice, after which the wires may be simply lifted from the twisting head.

Having thus described the invention, what is claimed as new, is

1. In a Wire splicing device, a frame includingside members having slots at their upper ends, bearing members secured on said side members, each bearing member comprising two halves combining to form a ring having an inlet slot, a head supported for rotation in the bearing members and having an enlarged portion provided with a transverse slot and with a threaded socket, a slotted twisting blade mounted in the transverse recess of the head, and a handle having threaded engagement with the socket.

2. In a wire splicing machine, a frame having side members provided with slots at their upper ends, a head supported for rotation between the side members and having an enlarged portion provided with a transverse recess, a twisting blade fitted in said recess, dowel pins extending through the blade and through the enlarged portion to assemble the blade with the head, and means for rotating the head.

In testimony whereof I afiix my signature in presence of two witnesses.
